Transmission Slipping

A slipping transmission is one of the most expensive failures to ignore.

Severity: High

What to Do Right Now

Check fluid first. If fluid is burnt or low, see a transmission specialist immediately. Continued driving turns a $200 fluid change into a $4,000 rebuild.

Common Causes

  1. Low transmission fluid: Cheapest first thing to check. Low fluid causes slipping. Top off carefully — overfilling damages the trans. Shop transmission fluid
  2. Burnt or contaminated transmission fluid: Fluid should be red and smell sweet. Brown fluid that smells burnt = trans damage. Shop transmission fluid
  3. Worn clutch packs (automatics): Internal wear causes RPMs to flare without acceleration. Major repair. Shop transmission
  4. Worn clutch (manuals): Engine RPM rises without speed gain — clutch is slipping. Shop clutch
  5. Failing torque converter: Shudders or surges, especially at low speeds. Shop transmission
